Delaware River reservoir levels have declined into the lower half of the drought warning zone (Fri., Oct. 13, 1995), triggering additional withdrawal restrictions for New York City and other communities, according to the U.S. Geological Survey’s Delaware River Master.

Rains from tropical storm Opal are expected to have little significant impact on long-term drought conditions in the eastern U.S., particularly ground-water levels, according to the U.S. Geological Survey.

A magnitude 7.0 earthquake occurred on southern Sumatra, Indonesia, at 2:09 p.m. EDT (local time on Sumatra 1:09 a.m., Oct. 7). The epicenter was about 105 miles southeast of Panang or 290 miles southwest of Singapore.

A magnitude 6.4 earthquake occurred Thurs., Oct. 5, 1995, in Alaska, about 40 miles northwest of Fairbanks, at 9:23 p.m. Alaska Daylight Time (1:23 a.m. EDT, Oct. 6), according to the U.S. Geological Survey.

A magnitude 6.9 earthquake occurred near the Peru/Ecuador border, in Ecuador, on Mon., Oct. 2, 1995, at 9:51 p.m. EDT (8:51 p.m. local time in S.A.), according to the U.S. Geological Survey.

"After seven months of near-stagnation, Alaska’s Bering Glacier resumed surging. Between May 19th and June 1, part of the glacier advanced almost half a mile (about 2,500 ft). As of mid-September, the surge was continuing," said Bruce F. Molnia, leader of the U.S. Geological Survey’s Bering Glacier Research Project.

Land subsidence, a potential geological hazard throughout most of California’s valleys, is the subject of a two-day symposium in Sacramento, Calif., that will honor one of the pioneers in California geology and groundwater studies.

Joseph F. Poland, whose memory will be honored with a special symposium at this year’s annual meeting of the Association of Engineering Geologists and the Groundwater Resources Association of California in Sacramento, Calif., Oct. 2-8, was a pioneer in the field of engineering geology and one of the world’s leading scientists associated with the United States Geological Survey.

Mr. J. Robert Porter is the recipient of the William T. Pecora Award, bestowed jointly by the National Aeronautics and Space Administration (NASA) and the Department of the Interior in recognition of outstanding contributions toward the understanding of the Earth by means of remote sensing.
